Answer: a. increase , b. decrease , c.increase

Explanation:

a. When the budget increases from $100 to $150 more books and movies tickets can be purchased at the current prices. attainable combinations would definitely increase.

b. When the price of movie tickets rises to $20, attainable combinations will decrease because less movie tickets will be attainable at the current budget of $100, previously we used to get 2 movie tickets for $20 now we get 1 movie ticket for $20, with a Budget of $100 and price of books remaining at $25 the combination sets attainable will decrease

c. when the price of a book falls from $25 to $15 attainable combinations will increase. When the price for a book falls to $15 per books, there is an extra $10 dollar ($25 -$15) available that can be used to buy more ticket movies or contributes towards attaining more books. When the price of books falls to $15, other factors remaining equal, attainable combinations sets will increase
